Voynich Manuscript: was the author left-handed?

Folio 57v, resembles the wheel of fortune card from the Visconti-Sforza Tarot deck (Figure 6). Both drawings represent the four stages of man: childhood, youth, adult and old age, showing the inevitability of life and death. The wheel was a medieval instrument of torture so this drawing could have a double meaning indicating that man has little control over the fickleness of fate.
